Title: Ant-protective cable
Inventor: TAKAHATA NORIO
IPC: H01B7/17
Filed: 1987-11-13
Abstract: PURPOSE:To obtain a good ant-protective effect by extruding to mould a sheath using compound pellets having organic phosphorous ant-protective agent applied on the surface or absorbed inside. CONSTITUTION:Ant-protective agent of organic phosphorous compound is applied on the surface of compound pellets or absorbed inside them. Though there is no particular restriction for the organic phosphorous ant-protective agent, tetrachloro, pyrida, etc., are especially suitable for wires and cables which require a long service life. For the compound to be moulded into a sheath, vinyl or polyethylene or the like are suitable which are often used for the sheath or wires or cables, though these are not the only example. Around a core wire 1 coated with insulation 2 is moulded a sheath 3 by extrusion using compound pellets having organic phosphoric ant-protective agent absorbed inside, for example, so an ant-protective cable is formed. The ant-protective cable is thus formed restricting thermal hysteresis of the ant-protective agent to the minimum decomposition, thereby reduction of ant-protective effect is prevented.
